NCERT Exemplar Class 8 Maths Chapter 12: Introduction to Graphs
Main Concepts and Results
- Graphical representation of data is easier to understand
- A bar graph, a pie chart and histogram are graphical representations of data.
- A line graph displays data that changes continuously over periods of time.
- A line graph in which all the line segments form a part of a single line is called a linear graph.
- For fixing a point on the graph sheet, we need two mutually perpendicular lines (in which horizontal line is called x axis and the vertical line as y axis) along with, x coordinate (abscissa) and y coordinate (ordinate) of the point. The process of fixing a point with the help of the coordinates is known as plotting a point in the plane.
- The relation between a dependent variable and an independent variable is shown through a graph.
